Toyota 4Runner Radiator Hoses

Radiator hoses are utilized to connect the rigidly mounted parts of the cooling system, such as the radiator, expansion tank, and heater core, with the engine which is experiencing vibrations. Clamps come into play when it is necessary to secure the hoses’ ends to inlets or nipples. Over the years, radiator hoses and clamps can deteriorate, become swollen or brittle. For this reason, it is recommended to replace them every 3 to 5 years. If radiator hoses or clamps get damaged, the coolant will flow to the ground, and the engine will overheat.

Unfortunately, drivers do report radiator problems on the Toyota 4Runner. Many of these issues occur due to faulty hoses, in particular. Some owners complain about the repeated cases of leakages, even after the hoses have been replaced. Moreover, there is an issue, called “the strawberry milkshake.” It happens due to corroded lower radiator lines which allow the engine coolant mix with transmission fluid. The resulting mixture resembles a strawberry milkshake. But the main thing is that the mixture can severely damage your automatic transmission. Therefore, regular coolant flushing is recommended.
